Graphing Inequalities

Question

Randy has a coupon for 20% off any purchase, with a maximum discount of 15%. What is the highest purchase price that will receive the full 20% discount?

Write an inequality to help you solve the problem.

Graph the solution on a number line.

Answer 1

did you me that the maximum discount is $15 not 15%. 15% makes no sense. 

 

So if this is correct then 

 

.2 x <= 15

so x <= $75

 

so the highest amount of the sale would be $75
